Abstract: This extended abstract describes some advantages and limitations of using Bluetooth® (BT) radios as a serial cable replacement between acoustic instruments and a laptop computer. BT radios are a relatively inexpensive method to communicate wirelessly with one or more acoustic instruments. A case study is presented where this technology was implemented to allow project personnel to check battery voltage, system status, and real-time flowrate and stage readings from 3 Sontek/YSI Argonaut-SW flowmeters. An application of integrating GPS data into a Teledyne/RD Instruments Streampro datafile using a wireless RS-232 serial communications is also summarized.
